Key takeaways
  • Your device or password manager keeps the passkey.
  • Add a backup passkey before you need one.
  • A passkey replaces your password, not every check.
  • Review withdrawal allowlists and set activity alerts.

Short answer

Add a passkey in your exchange security settings and confirm it with your device unlock. It takes the place of your password at login and, where your exchange allows it, approves withdrawals.

A passkey is a sign-in credential your phone or password manager keeps. It stays under your device unlock.

What to know before you start

A passkey replaces the password you type at login with the device unlock you already use, such as a fingerprint, face scan, or PIN. Where your exchange allows it, the same passkey can approve a withdrawal, so a stolen password is not enough. Support and rules differ between exchanges, so check both before you start.

Before you start

  • Look for a passkey option in security settings.
  • Check that passkeys can approve withdrawals.
  • Choose the device that will hold it.
  • Have your device unlock ready.

How to add a passkey to your exchange
